  1. Hypernuclear Spectroscopy Joerg Reinhold Florida International University for the Jefferson Lab Collaborations E97-104, E01-011, E05-115 DNP Town Meeting, Joerg Reinhold (FIU)

  2. Aspects of Hypernuclear Physics • Free from Pauli blocking • Deeply bound states • ~100keV intrinsic width • LS mixing (CSB, 3BF) • Baryon structure in the nuclear medium • Central and spin dependent LN intercations • Unified view of baryon-baryon interactions in SU(3) • Astrophysical aspects: hyperon matter, strange neutron stars, … DNP Town Meeting, Joerg Reinhold (FIU)

  3. L Hypernuclear Spectroscopy DNP Town Meeting, Joerg Reinhold (FIU)

  4. L Hypernuclear Chart DNP Town Meeting, Joerg Reinhold (FIU)

  5. g spectroscopy (KEK) DNP Town Meeting, Joerg Reinhold (FIU)

  6. JLab Hall A (E94-107) KEK Jlab: DE~650 keV Core excited states 12C strength well reproduced 16O strength off by factor of 2 Theoretical interpretation and publication in progress. DNP Town Meeting, Joerg Reinhold (FIU)

  7. Jlab Hall C (HKS) KEK Also 7Li, 12C targets (51V & 89Y for rate studies) DNP Town Meeting, Joerg Reinhold (FIU)

  8. Heavy L-Hypernucleiin the reaction KEK E140a: T. Hasegawa, et al., PRC53(1996)1210. DE~0.5 MeV; FWHM ~ 2.2 MeV Single particle motion over the full spectral range -> describe with mean field dynamics DNP Town Meeting, Joerg Reinhold (FIU)

  9. Sensitivity to coupling constants DE=1.65 MeV FWHM T. Hasegawa, et al., PRC53(1996) 2.2 MeV FWHM Hotchi, et al., PRC64(2001) DDRH: H.Lenske et al. Link free to in-medium coupling constants Free LN, hypernuclear, nuclear matter in the same framework Substantial SU(3) symmetry breaking DNP Town Meeting, Joerg Reinhold (FIU)

  10. BHF approach for hypernuclear matter (Hans-Joseph Schulze INFN Catania) Absolute energy scale in (e,e’K): DE ~ 100 keV DNP Town Meeting, Joerg Reinhold (FIU)

  11. Reaction spectroscopy (p,K) reaction spectroscopy established(BNL&KEK); L single particle levels up to A=208; hits ceiling at DE~1.7 MeV. (e,e’K) established in 2000; DE<1MeV (HNSS) (e,e’K) refined; E94-107 (Hall A) & E01-011 (HKS); DE~650keV g spectroscopy hyperball at BNL & KEK Data on LS in 13C The incredible shrinking nucleus: BE(2) in 7LLi Past Successes DNP Town Meeting, Joerg Reinhold (FIU)

  12. Jlab: reaction spectr. Light mirror nuclei (CSB) Medium to heavy nuclei Thin targets (isotopic enriched) Neutron-rich E05-115 approved: A~50 (V, Cr) Substantial $ from Japan (Tohoku University): HKS spectrometer for 2005, HES in 2007 JLab proposal: angular distributions Substantial $ from Italy (septa, RICH) JPARC: g-spectrosc.( ) Light nuclei LS-splitting High precision Day-1 experiments E05 & E13 at JPARC hadron facility US collaborators: FIU, HU, … (no contributions yet; several < $100k items identified.)
